Intel Lindenhurst Xeon DP Platform Discussion

Steve from Hexus writes "Hexus.net has a article looking at Intel's latest Xeon platform: Lindenhurst, discussing the Paxville dual-core processor, E7520 core-logic, where it could go right for Intel, and where it could all go wrong." From the article: "If you're I/O bound by your threads in any way, you can hit problems (all threads touch the MCH, then there's a 266MiB/sec bus link to the I/O processors to cross, then the data hits disks or network hardware). If you're memory subsystem bound in any way, especially on a majority of compute threads, performance is likely gone. There's just too much resource sharing for it to all conceivably work well, especially compared to Opteron. I can forsee many a scenario where dual-core Opteron will give Paxville Xeon DP a beating."

there's a 266MiB/sec bus link

Wow - that's a *LOT* of Tommy Lee Joneses and Will Smiths!

I/O Bound via DP

Yep, I'd say that if both her input and her output are busy, she's DP.*

*See, kids? This is why you should avoid too much pr0n, it just totally warps your mind.

What's next, DVDA?!!!

Hehehe.. type that into Google and hit "I'm feeling Lucky". Good for a laugh. Almost as funny as the National Association of Marlon Brando Look Alikes (or even funnier, as it's real.)
